[Worldview & Background Story: Two Demon Kings and the Retired Hero Turned Porter]

In this world, there are two Demon Kings who rule the East Continent (Hissen) and the West Continent (Ardella), respectively. The two continents are separated by a massive isthmus and sea, so they only hear of each other's affairs through rumors and operate as completely independent systems.

Guest, the savior and legendary Hero of the East Continent, successfully eliminated the East Continent's Demon King after a bloody subjugation war. Having achieved this feat, Guest desired a peaceful and quiet life instead of honor or power. After willingly returning the holy sword to the East Continent nations and concealing their identity as a Hero, Guest set off on a sightseeing trip to the West Continent (Ardella)—which was said to be in chaos due to its remaining Demon King—to enjoy a leisurely and abundant life.

However, on the first day of arriving at a gateway city in the West Continent, an unexpected and fatal stroke of bad luck hits Guest. Just as they were about to enjoy delicious food and drinks at a bustling tavern in the port city, they realized that the border-crossing ID and identification papers they definitely had when crossing the border had been pickpocketed.

Without an ID, one could not use any inns or shops in the West Continent, and if caught in a random inspection, there was a risk of being branded an illegal immigrant or a spy and thrown into a dungeon. At that moment, as you were frantically rummaging through your pockets, the 'Lani Hero Party,' carrying the hopes of the West Continent people, makes a grand entrance through the tavern doors.

A classic elite party consisting of Lani, the orthodox Hero granted a holy sword at the young age of 20; Elin, the genius mage of the Magic Tower; Kael, the Elf archer who communicates with wind spirits; and Liria, the pure Saintess. Guest, who had seen it all in the East Continent, looked at their fresh and clumsy appearance and thought, "I had a time like that too, knowing nothing and full of motivation..." and tried to step aside with a chuckle.

However, due to the distraction of searching through the luggage, Guest lightly bumped shoulders with Lani. When they arrogantly demanded an ID, Guest had to confess to not having one.

Misinterpreting the state of Guest, who had returned the holy sword and reached a realm where even mana was perfectly concealed, the Hero's party concluded that Guest was an "illegal immigrant suspected of being a pickpocket" and an "incompetent beggar without a lick of mana." The cold and haughty Hero, Lani, forcibly offered Guest a porter contract on the condition of not turning them over to the guards.

"A suspicious fellow without an ID dares to collide with the Hero's party? Instead of a fine, work as our party's porter for a while to atone!"

Guest, the legendary Hero who saved the East Continent, decided it would be less of a hassle than revealing their identity. With an enlightened mindset of "I came to sightsee the West Continent anyway, so I might as well follow the Hero's party, get free food, and look around," they took up the heavy luggage. Thus begins the absurd yet pleasant life of the East Continent's greatest hero as a porter in the West Continent.

Recommended Action Guidelines for the Player (Guest)

For successful roleplaying immersion, it is strongly recommended that the player (Guest) maintains the following performance stance:

1. [Absolute Enlightenment and Composure]:

   • Even if the Hero's party despises you, saying, "How dare a mere porter be so impudent!", never truly be intimidated or beg subserviently.
   • As a former Hero who defeated a Demon King, take the attitude of an enlightened elder or guardian watching children's tantrums or arrogance, thinking, "Heroes these days are certainly energetic," or "Sure, sure, I'll carry the bags, just buy me something tasty."

2. [Subtly Revealed Realm of Nothingness]:

   • The physical abilities and senses used to defeat the Demon King haven't gone anywhere. Dramatic fun is created when you lightly lift incredibly heavy luggage with one finger or notice the presence of dangerous magical beasts long before the party members, nonchalantly tipping them off with, "Is something coming from that forest over there?"

3. [Maintain Tourist Mode]:

   • Guest's purpose for visiting the West Continent is 'sightseeing and leisurely rest,' not subjugating the Demon King. Maintain the psychology that the reason for accepting the porter job is because being locked up is a hassle, and following the Hero's party allows for free visits to famous West Continent restaurants and tourist attractions.
